Description |
Uniprot | DEVELOPMENTAL STAGE: During seeds germination, detected in embryos. In vegetative tissues under iron-sufficient, restricted almost exclusively to vascular bundles of roots and leaves, and to the root exodermis. In response to iron deficiency, accumulates in all tissues of roots and leaves. {ECO:0000269|PubMed:21331630}. |
Uniprot | TISSUE SPECIFICITY: Expressed constitutively at low levels in the roots (PubMed:16887895, PubMed:21331630). Also observed in flowers, developing seeds, embryos and vascular bundles (PubMed:21331630). {ECO:0000269|PubMed:16887895, ECO:0000269|PubMed:21331630}. |

Description |
UniProt | Transcription activator that binds to the DNA motif 5'-CACGTGG-3' in the promoter of iron (Fe) deficiency-inducible genes as well as of genes involved in iron homeostasis, thus contributing to basal tolerance to iron deficiency, iron uptake from soil and iron transport, particularly during seed maturation and germination (PubMed:16887895, PubMed:17559517, PubMed:21331630, PubMed:26224556). Promotes the accumulation of mugineic acid family phytosiderophores (MAs) (PubMed:17559517). Required for ethylene-mediated signaling during iron deficiency responses (PubMed:21112958). Improves growth and yield, especially in calcareous soil with low iron availability. Promotes iron concentration in shoots and grain (PubMed:21331630). {ECO:0000269|PubMed:16887895, ECO:0000269|PubMed:17559517, ECO:0000269|PubMed:21112958, ECO:0000269|PubMed:21331630, ECO:0000269|PubMed:26224556}. |

Description |
UniProt | INDUCTION: Strongly induced in both roots and shoots during iron (Fe) deficiency stress (PubMed:16887895, PubMed:18025467, PubMed:19737364, PubMed:21112958, PubMed:21331630, PubMed:24280375). Ethylene enhances the iron deficiency-mediated induction (PubMed:21112958). Induced by arsenate (AsV25 and AsV50); this induction is repressed by nitric oxide (NO) (PubMed:26793232). Accumulates under cadmium (Cd) stress; this induction is inhibited by the DNA methyltransferase inhibitor 5-aza-2-deoxycytidine (Aza) (PubMed:27412910). {ECO:0000269|PubMed:16887895, ECO:0000269|PubMed:18025467, ECO:0000269|PubMed:19737364, ECO:0000269|PubMed:21112958, ECO:0000269|PubMed:21331630, ECO:0000269|PubMed:24280375, ECO:0000269|PubMed:26793232, ECO:0000269|PubMed:27412910}. |
